RAIL-JOINT.

SPECIFICATION forming part of Letters Patent N 0. 708,009, dated September 2, 1902. Application filad Jannai y 6, 19(l2j. I Serial No. 88,518. (No model.)

To all whom, it may concern:

Be it known that I, MAX BARSCHALL, a subject of the King of Saxony, residing. atthe city of New York, borough of Manhattan,

county and State of New York, have invented certain new and useful Improvements in Rail- Joints, of which the following is a specification.

My invention relates to rail-joints, and has for its object to provide a safety-rail or auxiliary support at the joint of the main rails and to so construct the auxiliary rail-that it will be exceedingly strong and readily manufactured by rolling. 1.

My invention will be fully described hereinafter and the features of novelty pointed out in the appended claims. 7

Reference is to be had to the accompanying drawings, in which 1 Figure 1 is a cross-section of one form of my improved rail-joint. Fig. 2 is a similar view of another form of myinvention. Fig. 3 is a plan thereof, and Fig. 4 is a cross-section of still another form of my improved rail- My improved rail-joint is constructed on the principle ofthe invention shown in the United States Patent No.. 532,431, granted on JanuaryS, 1S95,'toG.-A. Hoffmann and M. Friedlander, and is a further development of saidpatented invention, which-has been assigned to the firm of Ausfuehrungen fuer Eisenbahn Oberbau, Abth. Stossfangschiene, Siegm. Eppenstein, of which I am a member. In this patent thereis shown an auxiliary rail which is arranged alongside the main rails, at the joint thereof, and has its head curved or beveled downwardly at the ends and also sloped'transversely. In my present 0 invention the same features may be employed together witha filling-piece or fish-plate which is located between the main rails and the auxiliary rail, as described in said patent. It has been found desirable in somecases to give an increased strength to the auxiliary rail. The most obvious course would be'to simply increase the thickness of the web-0f said auxiliary rail. This, however, is open to the objection that either the auxiliaryrail or thefilling-piece or fish-plate will become unsymmetrical in this case. To overcome the difficulty and to secure a proper engagement of the several parts of the joint, as will be set-forth in detail hereinafter, I do not increase the thickness of the web of the auxiliary rail at those points at which said web is in contact with the filling-piece, but I do give an increased thickness to the web of the auxiliary railbetween those points.

As illustrated by Fig. 1, A is one of the main rails, B is the auxiliary rail, having the transversely-sloping top surface B and havingits base B recessed upon one side so as to accommodate (with play) the base of the main rail, and O is the double-headed fillingpiece. This filling-piece engages the heads and bases of both rails and also the webs of the rails adjacent to the heads and bases. The

v whole structure is held together. by bolt D,

working injconnection with a fish-plate E,

washer F, and nut G. This bolt may have a relatively tight fit in the Webs of the two rails; but the bolt-holes C in the filling-piece are lengthened, so as to allow of somevertical play. The web of the auxiliary rail has two portions B which are symmetrical relatively to the center of the rail-head. Between these two webportions B is located an outwardlybulged unsymmetrical web portion B and in this'web portion the bolt-holes are provided.

In Fig. 2 the constrliction' differs from that just described merely by the fact that the enlargement B of the auxiliary-rail web is located upon the inner surface of said web. It will be observed that in this case the heads of the filling-piece C are not in engagement with the enlarged portion B so that there is some play allowed for a slight up or down'movement of the filling-piece.

D of the bolt D, so that said bolt will be held positively against turning, thus reducing the liability of the nuts G becoming loose.

I desire to call particular attention to the fact that the filling-piece C is symmetrical, so that the web of said filling-piece is vertical below the abutting side surfaces of the railheads. The web of the main rail is of course symmetrical relatively to the head thereof, and the webportions B of the auxiliaryrailare also symmetrical relatively to the head of the auxiliary rail, the full width of said head being equal to the width of the main-rail head. I thus obtain a very strong construction without destroying the symmetrical arrangement of the parts. With an unsymmetrical arrange ment there would arise strains tending to to turn or tip either the main rails or the auxiliary rail sidewise. A11 important practical advantage of the constructions shown is that the auxiliary rail may be produced in a rollin g-mill even when the groove 13 is employed, it being understood that this groove would extend uniformlyfrom end to end of the auxiliary rail.

I claim as my invention and desire to secure by Letters Patent 1. Arail-joint comprisingin combination a main rail, an auxiliary rail, the head of which abuts against the main rail, a double-headed filling-piece arranged between the webs of the said rails, the web of the auxiliary rail being of relatively small thickness at the points where it is engaged by the said fillingpiece, and of increased thickness between said points, and means for connecting the auxiliary rail with the main rail.

2. A rail-joint comprising in combination a main rail, an auxiliary rail, the head of which abuts against that of the main rail, said auxiliary rail having a web with relatively thin portions adjacent to its head and base and with a central portion of greater thickness, a filling-piece located between the webs of the main rail and the auxiliary rail and provided with heads which engage the web of the auxiliary rail at the thin portions thereof, and bolts passing through the webs of the rails and loosely through the web of the filling-piece.

3. A rail-joint comprising a main rail, an auxiliary rail abutting against it and provided with an outwardly-thickened web portion provided with a longitudinal groove, a filling-piece located between the webs of the main rail and the auxiliary rail, and bolts connecting the said rails and having angular heads seated in the groove of the auxiliary rail.

4. A rail-joint comprising a symmetrical main rail, an auxiliary rail having a head of the same width as that of the main rail, and also having a web located symmetrically to the head adjacent to the said head and to the base, and of relatively small thickness at those points, the intermediate or central portion of the web being of increased thickness, a double-headed filling-piece, the heads of which engage the web of the main rail and also engage the web of the auxiliary rail at the'thin portions thereof, and connectingbolts extending through the webs of the'rails and loosely through the web of the fillingpiece.

MAX BARSCHALL.
